Installation
2.1 Use PoE or external Power Adapter
H83 color screen IP phone
, called as ‘H83’ hereafter, supports two power supply modes, power supply from
external power adapter and H83 also supports 802.3af Class 1 Power over Ethernet (PoE) complied switch.
PoE power supply saves the space and cost of providing the phone additional power outlet. With a PoE
switch, the phone can be powered through a single Ethernet cable which is also used for data transmission.
By attaching UPS system to PoE switch, the phone can keep working at power outage just like traditional
PSTN telephone which is powered by the telephone line.
For users who do not have PoE equipment, the traditional power adapter should be used. If the phone is
connected to a PoE switch and power adapter at the same time, the power adapter will be used in priority and
will switch to PoE power supply at power failure on the power adapter.
Please use the power adapter supplied and the PoE switch met the specifications to ensure the phone work
properly.
